Who invented the Caravel, and when and why.

The Caravel was slightly smaller than the Carrack. It was generally used for carrying cargo and fishing. Prince Henry the Navigator of Portugal created the Caravel for long distance trade. It boasted two or three masts that had interchangeable sails. Square sails were used for open water while lateen sails were used for shoreline sailing. The also had a rounded bottom, making them faster than other vessels of their time. Subsequently, they were also favored by pirates. Columbus’ ships, the Nina and the Pinta, were both designed as Caravels.

Hopefully my answer help :)

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.

by 1880, germany had more rail lines than great britain and russia.
